Description

MÁQUINA PARA CORTAR PELES E SEMELHANTES E MATERIAIS EM FORMA DE FOLHA EM GERAL, COM MESA DE TRABALHO DE ACESSO SIMPLIFICADO.MACHINE TO CUT SKIN AND SIMILARS AND MATERIALS IN SHEET SHAPE IN GENERAL, WITH SIMPLIFIED ACCESS WORK TABLE.

1. Refere-se o presente pedido afeto ao setor coureiro, a uma máquina de corte de peles e similares dotada de uma mesa de corte adaptada para receber peles cujas dimensões excedam as dimensões de cada um dos quatro lados da mesa.1. This request refers to the leather sector, to a machine for cutting skins and the like, equipped with a cutting table adapted to receive skins whose dimensions exceed the dimensions of each of the four sides of the table.

2. As máquinas de corte de peles de controle numérico conhecidas hoje, são munidas de um carro movente x-y e de uma mesa de trabalho fixa com sucção, adaptadas para processar peles por porções sucessivas, desenvolvendo as operações de corte sucessivamente em porções limitadas de peles devido as dimensões da mesa de trabalho, as quais , juntamente com a área de trabalho, são dependentes das características das gruas de ponte e da necessidade de visibilidade do operador durante a operação de colocação de peles na área ou na mesa de trabalho.2. The numerical control hides cutting machines known today, are equipped with an xy moving carriage and a fixed suction work table, adapted to process hides in successive portions, developing the cutting operations successively in limited portions of hides due to the dimensions of the work table, which, together with the work area, are dependent on the characteristics of the bridge cranes and the operator's need for visibility during the operation of laying skins on the work area or table.

3. As máquinas de corte de peles com uma mesa de trabalho fixa com sucção são divididas entre máquinas de estação única e máquinas com estações duplas oscilantes, sendo que nas de estação única as operações de colocação e descarga de peles e das cabeças de corte são desenvolvidas sequencialmente, nas máquinas de estações duplas oscilantes, o operador e a cabeça de corte se alternam entre as duas estações para desenvolver as operações em paralelo.3. The fur cutting machines with a fixed suction work table are divided between single station machines and machines with double oscillating stations, whereas in single station machines the operations of placing and unloading skins and cutting heads are developed sequentially, in double oscillating station machines, the operator and the cutting head alternate between the two stations to develop operations in parallel.

4. A largura de cada estação é adaptada para acomodar uma porção estatísticamente significante de peles, conforme a largura das peles, enquanto a profundidade da área ou da mesa de trabalho da estação é limitada pela necessidade do operador ter visibilidade para a colocação das peles, podendo dessa forma conter apenas porções sucessivas das peles que são feitas para deslizar sequencialmente ao longo da direção longitudinal.4. The width of each station is adapted to accommodate a statistically significant portion of skins, depending on the width of the skins, while the depth of the station's area or work table is limited by the operator's need to have visibility to place the skins, thus being able to contain only successive portions of the skins that are made to slide sequentially along the longitudinal direction.

5. O corte das peles é desenvolvido por um carro ferramenta, que desliza na direção da profundidade da mesa de trabalho ao longo de uma ponte que é movida ao longo da largura da mesa, sendo que na traseira essa ponte transpõe um bolso de retenção o qual permite acomodar a porção de pele ainda a ser trabalhada, enrolada em si mesma, permitindo posicionar e trabalhar na mesa de trabalho ou na área de trabalho, peles cuja largura está entre a largura máxima da estação de trabalho e cujo comprimento é maior do que o comprimento do campo de trabalho, uma vez que a porção excedente pode ser enrolada em si mesma e acomodada no bolso de retenção, não sendo possível fazer o excesso de pele se projetar na frente, devido a presença da guia frontal na grua da ponte.5. The skins are cut by a tool carriage, which slides in the direction of the depth of the work table along a bridge that is moved along the width of the table. which allows to accommodate the portion of skin still to be worked, wrapped in itself, allowing to position and work on the work table or in the work area, skins whose width is between the maximum width of the workstation and whose length is greater than the length of the working field, since the excess portion can be rolled up in itself and accommodated in the retaining pocket, it is not possible to make the excess skin protrude from the front, due to the presence of the front guide on the bridge crane.

6. O objetivo da presente invenção é fornecer uma máquina de corte de peles e similares que permita trabalhar peles com dimensões que excedam a área de trabalho dos quatro lados da mesa ou da área de trabalho, e também que tenha acesso simplificado que permita trabalhar também em porções exclusivamente centrais da pele, com esta se projetando dos quatro lados da mesa de trabalho.6. The purpose of the present invention is to provide a machine for cutting skins and the like that allows to work skins with dimensions that exceed the working area on the four sides of the table or the work area, and also that has simplified access that allows working also in exclusively central portions of the skin, with it protruding from the four sides of the work table.

7. Tal máquina inclui um suporte para apoiar a mesa de trabalho e os elementos de corte adaptados para serem movidos por meio de controle numérico ao longo dos contornos das formas a serem cortadas, onde as extensões imaginárias dos 3 lados da mesa de trabalho não encontrem obstáculos devido aos elementos de corte e seus suportes, sendo o quarto lado da mesa transposto por um braço cantilever que apóia os elementos de corte.7. This machine includes a support to support the work table and the cutting elements adapted to be moved by means of numerical control along the contours of the shapes to be cut, where the imaginary extensions of the 3 sides of the work table do not find obstacles due to the cutting elements and their supports, the fourth side of the table being transposed by a cantilever arm that supports the cutting elements.

8. São apresentados em anexo, desenhos esquemáticos explicativos, onde partes iguais ou similares levam a mesma numeração.8. Attached are explanatory schematic drawings, where the same or similar parts have the same numbering.
